    @tom I'm not having the same issue with GPS lock. I can get a GPS lock, but my GPS is showing as disabled in QGC. Is there a PX4 parameter loaded on the Sentinel's that defaults them to disable GPS? Changing the EKF2_AID_MASK to enable GPS doesn't due anything. *Ignore this part, just didn't have COM_ARM_WO_GPS set to 0 Also, I'm still concerned about the constant MAG#0 timeout errors, the unstable/unrealistic position estimates I'm getting for Local Position NED in QGC and the high loss rate I'm getting over mavlink. Do you have any suggestions for troubleshooting and is there a way to synchronize the clock on the voxl2 with the clock on the GSC? Thanks

    Hi @A-Evans This is our current WiFi solution for Voxl2, or any ModalAI board with a standard USB2 4-position JST GH port. https://www.modalai.com/products/wifi-usb-cable-add-on?_fid=da227b041&_pos=1&_ss=c If you want to use our 10-pin USB3 format connector for the Alpha USB Dongle, then you can also consider using this cable: https://www.modalai.com/products/mcbl-00022 Note: We use Alpha WiFi since it's NDAA compliant You are free to use any WiFI USB dongle sourced at the UK, and make your own cables for USB2 (not too hard for proto-type builds).

    @Jgaucin you can use voxl-portal to view the output of all of the image sensors on the drone. The Sentinel has forward and rearward stereo depth pre-calibrated and tested in the factory https://docs.modalai.com/voxl-portal-cameras/ this might also be useful https://docs.modalai.com/calibrate-cameras/

    @Eric-Katzfey I think it probably makes a lot of sense to leave it on there and just call it out more in unboxing. We purchased a number of platforms and it only came up with 2 of them.

    @Neil-Huang Yes, if TBS side doesn't use 250000 then that line would need to be changed.

    @martygp95, Yes, powering the Sentinel with a 4S is fine. Just be sure NOT TO FLY with it. The tuning for the drone was done around the 3S and if you attempt to fly with the 4S, then there could be detrimental flight-performance. The APM on the Sentinel can handle 2S-6S [2 cell (6.4V min, 7.4V nom, 8.4V max) 6 cell ( 19.2V min, 22.2V nom, 25.2V max)]. You can find info about the APM here Hope that helps

    Hello, Can you please check the vehicle's attitude (roll, pitch, yaw) when it is sitting flat, right before take-off? You can look at PX4 logs or live using GCS. If the IMU is not calibrated properly, and the vehicle thinks that it is tilted, it will try to compensate for it by tilting in opposite direction, so it can appear as if one of the motors is not able to spin faster, when in fact the flight controller could be commanding it to spin slowly. This is just one reason why this could be happening, so it is worth checking.

    The VOXL 2 found on the Sentinel has 4x more computing power than the VOXL 1 found on m500. We do not know anything about UAV Toolbox or how to support it

    Any Hobby LiPo charger should work fine. The following supports 1S to 6S and from the picture it looks to come with an XT60 connector as well https://www.amazon.com/Charger-Battery-Balance-Discharger-Adapter/dp/B07R18YNZQ/
